Cummins-developed diesel being developed for Nissan – Click above for image gallery

Is Nissan making play for diesel? According to our friends at PickupTrucks.com, it sure seems that way... at least for pickup truck duty. Thanks to some cash from the U.S. Department of Engery, Cummins is developing a four-cylinder oil-burner, and it's currently nestled under the hood of a Nissan Titan. Cummins is looking to bump fuel efficiency by 40 percent compared to the current V8 mills being employed.

The current fuel economy target? A combined rating of 28 miles per gallon, which would mean the diesel-equipped Titan would be running at over 30 miles per gallon on the highway. Cummins is said to be targeting 220 horsepower and 380 pound-feet of torque, and currently, the prototype engine is able to produce 350 pound-feet of torque at 1,800 rpm.

      I second the "About Time" comments. Why this has taken so long I have no idea.

      DOE says diesel is good...EPA says those are fightin' words....

      If ever a vehicle needed a diesel it is the Titan. At 30 mpg Nissan might finally be able to sell a noticeable number. The other big point to make is that this should also show up in the NV van. They need it for that market because there are some customers who will not buy anything that is not diesel powered. 380 ft/lbs of torque is plenty for this application. This engine makes about the same horsepower and a lot more torque than all those 4.6 two valves running around in millions of F150s.

        I know arthritic hamsters with more torque than those 4.6 Ford V8's, and a 4 speed isn't helping.

        I forgot about the NV. Now that engine makes sense.

      I hope this engine gets used in more then just a large truck. 220hp with 380ft-lb would be a blast in a light car.

        Absolutely agree - a mid-size sedan (or station wagon) with this engine and a manual transmission would have tremendous performance - both in 0-60 and economy.

      So Nissan is the company with the balls to make this happen....never would have saw that coming. Can't wait to see one of these in person =)

      Nissan sells Navara and Pathfinder in Europe with either 2.5 liter 4 cylinder or a 3.0 liter V6 diesels. The 2.5 liter engine is rated at 190 hp and 450 Nm, that 332 pound-feet, 27.7 mpg (US gallon). The V6 is 231 jp and 550 Nm (392 pound-feet) with 25.3 mpg. I understand that Titan is a rather different animal... and that Cummins are specialist company. But given the new engine specs are, it looks a tad like a needless duplicity to develop an engine that's very similar to what Nissan already has available.

        It's a government project, not a Nissan one. And well, needless duplicity is one of the government's specialities.

        I suspect Nissan diesel engine production for the 2.5 L4 and 3.0V6 is limited and that there isn't enough production to go the the US...or the US price premium won't sell/make up for the certification required. Don't forget a new engine generally requires doing the crash tests again.

      bout dam time. hope they can offer it at a relatively low price point, too.

      Those numbers look close to the new VM Diesel in the Jeep GC (241HP & 406LbFt) while doing so on 2 less cylinders (and substantially lower weight probably.)

        Sad but not surprising. Ford and GM are frequently telling us that we don't want diesels, just like we don't want manual transmissions. Now imagine this engine or something similar in a Ranger size truck.
